Patented'June 6,1916.

Application filed August 15, 1910, Serial No. 577,369. Renewed September 1, 1915. Serial No. 46,573.

' To all whom it may concern:

State of New Jersey, have invented certainnew and useful Improvements in B0ttle- Making Machines, of which the following is a specification.

The invention relates. to bottle-making machines for the formation of bottles or other containers from paper or similar flexible material suitably'tempered and treated with an adhesive. I

The objects of the invention includethe provision of a flexible form for shaping bottles having contracted necks and mouths, means for adjusting the form and clamping thereto a previously formed bottle-blank constituting the bottom of the bottle to be formed, means. for rotating the form to shape thebottle thereon, means to unite the bottom-blank and side walls of the bottle, means for shaping the contracted neck and mouth, means for applying reinforcing bands for the formation of the mouth, and

means for collapsing and withdrawing the form from the bottle thus shaped.

Further objects include certain details of construction hereinafter set forth.

In describing the invention in detail reference ishad to the accompanying drawings, forming part of this specification, and wherein like characters of reference are used to designate like parts throughout the several views, and in which:

Figure 1 is a ground plan of the machine embodying the present invention; Fig. 2, is a side elevation, with the front frame removed, and parts shown partially in section; Fig. 3, an exterior end elevation; Fig. 4, a transverse sectional elevation on line m-m, Fig. 2; Fig. 5, an enlarged longitudinal sectional View of the form, shown in connection with its supporting parts; Fig. 6, an end view of the ottom of the form; Fig. 7, a cross-sectional view showing a portion of the covering of the form in connection with one of the ribs and the expansion links; and Fig. 8 is a transverse section of a fragment of the tapered neck-forming portion of the form, showing a recess in the cover for receiving the creasing blades of the forming rolls.

In the drawings, numerals 1 and 2 designate respectively the front and rear main frames of the machine, laterally connected by the cross-braces 3, 4, 5, 6 and 7, and provided with the inwardly-extending ways 8 for slidingly supporting the cross-heads 9 and 10, which, together with the bearing 11, formed on cross-brace 5, rotatively support,

the form-shaft 12. For rotating this shaft a gear 13 is provided, having an outwardlyextending hub 14, journaled in bearing 11, and positioned therein by collar 15. An inwardly-extending key 16 is fixed within the hub of the gear and slidingly engages a keyway 17 formed longitudinally in the shaft for permitting a lengthwise movement of the latter.

Intermediate of its length, the form-shaft 12 is provided with a sleeve 18, which is fixed thereon and mounted for rotative movement in the cross-head 9, the sleeve be ing positioned. in the latter by the outwardly-extending side flange 19 and the set collar. 20. The sleeve is further provided at its inner end with an annular recess 01'' counter-bore for slidingly receiving the tubular end of a head or hub 21, mounted for longitudinal sliding movementupon the formshaft, and. arranged for'rotation therewith by a key 22, fixed in the, huband engaging a key-way 23, in theyshaft, as shown. in

- dotted lines in Fig. 5 I The' l1ead 0r hub 21 is retained for rotative movement in the cross-head. 10 by the set-collar 24. An an nular recess or counter-bore is also provided in the tubular end of this hub adjacent the sleeve 18, and within said recess is loosely mounted a spirally-wound compression spring 25, the ends of which abut the terminal walls of the recess of the hub and sleeve and normally tend to urge or slide the former inward against the stop-collar 26 and in opposition to the fixed sleeve, the stop-collar being longitudinally adjustable on the shaft by the set screw 27.

The form, as shown in detail in Figs. 5, 6

and 7, is carried upon the overhanging inner end of the form-shaft 12, and includes a frame composed of a plurality of extensible bars or ribs, each consisting of an inner section 28 and an outer section 29, U-shaped in cross section, and pivotally connected together at 30. The inner. sections of the ribs are hingedly connected at their inner ends by the ring 31 to the two-part annular blocks 32, having radial slots to receive the ribs, and provided with detaching means to hub 21. Also, detachably fixed to shaft 12 are similar two-part blocks 33 and 34;, having rings 35 for pivotally connecting the inner ends of the expansiondinks 36, the outer ends of the latter being pivotally connected to the several rib-sections comprising the frame. Upon this frame, and conforming therewith, isdetachably secured an outer flexible cover 37, preferably formed of rubber and provided with inwardly-extending ridges 38, connected to the ribs of the frame in any suitable manner, as by a pin 39 fixed therein and extending through slots in the ridges.

From the foregoing description pertaining to the collapsible mandrel it will be understood that said mandrel embodies a ro tatable and reciprocable mandrel. shaft, a series of bars 29 linked to the mandrel shaft so "as to be retained in parallel relation therewith, a second series of bars 28 having pivotal connection with the mandrel shaft, said second series of bars having pivotal connection, also, with the bars of the first series, and said second series of bars being adapted to assume positions inclined to the axis of the mandrel shaft and to the bars of the first series, and means operated by an endwise movement of the mandrel shaft for moving the bars of the two series to their expanded operative positions and, also, to their collapsed positions.

As locked in the extended position indicated by the full lines, it will be evident that the form may be rotated to shape a bottle thereon, and that by sliding the shaft through the hub 21 to the engagement of the latter with the stop collar 26, the form will be collapsed and assume the position indicated by dotted lines, the flexible parts of the cover between the ribs folding upon themselves, and the whole sufficiently reduced in size to readily permit of its removal through the contracted portion of the formed bottle by the continued forward movement of the shaft. For effecting this longitudinal movement of the form shaft, an oscillatory arm 40 is provided and connected at its upper end by trunnions 41 to bosses 42, formed on the cross-head 9, which latter is arranged to slide horizontally back and forward on the ways 8, the sliding connections thereto being of any approved construction. The crosshead 9 being longitudinally fixed upon the form-shaft, as above described, and the cross-head 10 longitudinally slidable thereon. to a limited extent, corresponding to the movement necessary for the extension and collapse of the form, it will follow that the latter cross-head will travel with the former one overthe ways and be normally held separated for the collapse of the form by the compression spring 25, the outward extreme of movement of the cross-head 9 being indicated by the dotted lines 9. Stopscrews 43 are adjustably secured in the cross-head 10 for limiting the latters inwardmovement by 'the engagement of the projecting screw-end with the fixed crossbrace 4. Upon the inward or forward move ment of the form shaft and connected crossheads, the form will remain collapsed until the movement of cross-head 10 is arrested, from which point the form will be gradually extended by the continued movement of the shaft and cross-head 9, which effects a compression of the spring 25 and causes an outward movement of the expansion-links 36.. It is to be noted that the parts as thus arranged provide for the expansion and contraction of the form without necessitating a longitudinal movement thereof.

Upon the inner free end of the form-shaft a thread 44 is provided which is engaged by a nut 45, which serves to detachably secure a section of the two-part block 34, and is also provided with an outwardly-projecting conical end 46, conforming with the centrally-cupped portion of a bottom-blank 47,

constituting the bottom of a bottle, and

shown positioned thereon in dotted lines. This nut is further provided with an outweirdly-extending flange 48, suitably recessed to form clearances for the movement of the several expansion-links 36.-

For centralizing and clamping the bot tom-blank to the form, a hub 49 is employed, having a head 50, provided with a central recess conforming of the bottomblank. The hub is fixed upon clamp-shaft 51, and is journaled in cross head 52, in which. it is positioned by the collar 53, this cross-head being arranged to slide on ways 54, formed on the front and rear main frames, in a manner similarly described for cross-heads 9 and 10. For rotating clamp-shaft 51, a gear 55 is provided which is formed with an extended hub 56, journaled in a bearing 57, of cross-brace 3, the gear being positioned by the collar 58, secured to the hub. A drive-key 59 is fixed in. the gear and slidingly engages an extended keyway 60 in the clamp-shaft to rotate the same and to permit of relative longitudinal movement, this latter movement being efi'ected by the rock-arm 61, having at its upper end a drive-pin 62 which is journaled in a lug 63, formed on the crosshead 52.

Arranged above and below the form and coacting therewith, are the forming-rolls 64 and 65, respectively fixed upon the shafts 66 and 67, which are j'ournaled in boxes 68, slidably mounted upon ways 69, similarly disposed on the cross-braces 3 and 4.

Springs 7 0, having tension-adjusting screws.

71, are provided for each of the boxes and yieldingly urge the rolls into action with the form. Each of the forming-rolls is conwiththe cupped portion structed with a smooth cylindrical portion outwardly-tapered or frusto-conical portion 73 to engage and shape the contracted neck of the bottle. Projecting from, and equally spaced about the peripheral surfaces .of this latter portion of the rolls, and radially fixed therein, are a series of creasing or tucking blades 74, which coact with recesses 75, formed in the corresponding portion of the form, the projection-of the blades above the,

surface of the rolls being variable with respect to their length to accord with the superficial variation of the bottle for creasing the material of the latter to form uniform inwardly-extending plaited ribs and present a smooth exterior surface.

For imparting motion to the machine, a driving-pulley 76 is provided and fixed to one end of a main-drive-shaft 77, which is mounted for rotation in bearing 78, formed on the cross-braces 3 and 5. To this shaft are fixed the gears 79 and 80, which intermesh with lower idler-gears 81, shown in dotted lines in Fig. 3, the latter gears being loosely mounted on studs 82, fixed in the cross-braces 3 and 5. Through these idlers the gears 79 and 80 drive respectively the form-shaft gear 13 and the clamp-shaft gear 55 at a uniform rate of speed,the shafts thereof being axially disposed in a common line to effect a register of their adjacent interlocking ends to clamp the interposed bottom-blank and provide an added support for this "end' of the form-shaft. Upon the forming-roll shafts 66 and 67 are respectively fixed the gears 83 and 84, which are driven from the clamp-shaft gear 55. A

chain-wheel 85 is fixed on the opposite end of the main driving-shaft 77, and carries a drive-chain 86, engaging a larger wheel 87,

, fixed upon shaft 88, the latter being jourinterior of the side-frame '1. 88 is fixed a bevel-pinion 91, whichengagesnaled at its outer end in a bearing 89, formed on the cross-brace 6, and at its. inner end in a-journal-box90, secured upon the Upon shaft a bevel-wheel 92, secured upon shaft 93, the latter being mounted 1n bearing formed in the side framesl' and 2. A cam-wheel 94 is fixed .upon the latter shaft and engages a roller 95, mounted upon a central stud, secured to the connection-rod 96, which is provided with a slotted end 97 engaging shaft 93. At its opposite-end the rod is pivotally connected at 98 to the oscillatory arm 40 for imparting motion thereto. The above system of gearing extending from the mam shaft and "driving the form-shaft and the oscillatory arm is continuously driven and so proportioned that aplurality of turns of the form will be made to one backward and forward movement of'the arm, constltutlng a cycleof the machine.

The oscillatory arm 40 is pivotally mounted at its lower end upon a stud 99, fixed in pin 101, fixed to the bracket 102, of the cross-brace 7. qAs thus arranged the arm 40 atits upper endwill have ahorizontal ,path'maintained by the cross-head 9, and at its lower end its movement will be in a circular arc about the pin 101. Upon the arm 40 is secured a stud 103, upon which is hingedly mounted a box 104, having a central aperture to slidingly receive the outer end of an actuating-rod 105, an intermediate portion of which is threaded at 106 to adjustably engage the double nut 107, which serves as an abutment for the engagement of the'box 104. At its inner end the rod 105 is pivotally mounted upon a stud 108, fixed to the lower end of rock-arm 61, and upon this stud is also pivotally mounted one end of a spring-rod 109, the opposite end of which passes through a'perforation in the crossbrace 6 and is provided with a screw thread engaged by an adjustable stop .-nut 110. Loosely surrounding the rod is a spiral compression spring 111,. one end of which engages the cross-brace while its opposite end thrusts against a shoulder 112 formed on the rod, and yieldingly urges the lower end of rock-arm 61 inward. This rock-arm is pivotally supported intermediate of its ends upon a stud 113, fixed to a vibratory arm 114, which latter is pivotally mounted upon a pin 115, fixed to the bracket 116, formed on the cross-brace 6. As thus supported for movement about the pin 115, the upper end of the rock-arm is free to move horizontally and actuate the cross-head 52, the inward or clamping movement ofwhich is effected by the latter portion of the inward movement of the arm 40, which movement is transmitted through the hinged box 104, nut 107 and actuating-rod 105 to the rook-arm 61, the nut serving by its adjustment upon the rod to vary the clamping tension upon the blank 47. During this forward movement of rod 105, the spring-rod 109 is also moved in a like direction for the compression of spring 11 1, which latter upon its release, during the return movement of rod 105, serves to 1mpart a return movement to the rock-arm 61 the sheet is carried around thereby a num ber of turns corresponding to the number of layers of material required for the forma tion of the bottle, during which rotative movement the upper forming-roll similarly acts to shape the bottle and to equalize the stress upon the form from the oppositely disposed roll. For additional security the margin of the sheet is turned over and secured to the innersurface of the flange of the bottom-blank, which operation is effected by the forming-blade 119, which is secured to the cross-head 52 and serves to gradually turn inward the damp adhesive margin for the successive engagement of presser-rollers 120. These rollers are yieldingly mounted in blocks 121, adjustably secured to the adjacent cross-head, and act by rolling pressure upon the opposite surfaces of the flange to afiix the margin thereto. Presser-rollers are also provided for shaping the mouth portion of the bottle and affixing an adhesivelyprepared band 122. These resser-rollers, indicated by the single roller 123, yieldingly mounted upon the block 124, adjustably secured to the cross-head 10, coact with the forming sleeve 125, fixed upon the form-hub 21, shown in Fig. 5.

The cam-wheel 94, which makes one revolution per cycle of machine, is arranged with a concentric cam portion which holds the arms 40 and 61 in their inward'extreme of movement during the formation of the bot tle, from which point a rise in the cam causes arm 40 to move outward, the initial portion of which movement acts through rod 105 to release spring 111 for effectingthe outward movement of arm 61 to an extent limited by the stop-nut 110, the initial movement also acting to separate cross-heads 9 and 10 for the collapse of the form. Upon the continued outward movement of arm 40, the pivotally-connected box 104: slides loosely along the outer end of rod 105, and the crosshead 9 is also driven to its outer extreme of movement for the withdrawal-of the collapsed form from the finished bottle. During the withdrawal of the form, the bottle is retained between the rotating formingrollers 72 by the tucking-blades Hand the suitably-positioned back-stops 126, fixed to the frame of the machine. Upon the complete withdrawal of the form, the yieldinglysupported inner shaft-end of the upper forming-roll is slightly raised, in any convenient manner, for the release of the tuckingblades, which permits theforward discharge of7the finished bottle over the delivery bars 12 For feeding the bottom-blank to the machine, downwardly-inclined feed-bars 128 are used, and in connection therewith a mov-- able stop-lever 129 is arranged which permits the feeding of a single blank at a time to the guide-bars 130, which serve to position the blank approximately central with respect to the form, such positioning being effected while the cross-head 52 and its connected presser-rollers 120 are in their outer extreme of movement.

The continued rotation of the cam causes a return or inward movement of the arms 40 and 61 for the repositioning and expansion of the form and the clamping of a new blank thereto for the formation of a new bottle.
